STOVE-DOOR IEIOUNTING.

Application filed August 2-0, 1926. Serial No. 130.5%.

Ihis invention relates to door mountings and is designed moreparticularly for use with stove doors, such as the doors of ovens andbroilers.

One object of the invention is to provide such a door mounting whichwill be simple in its construction; which will be inexpensive tomanufacture; and which may be easily installed.

A further object of the invention is to provide such a mounting whichwill require no projections or housings on the outer surfaces of thestove front and door, thus permitting the use of a smooth front.

A further object of the invention is to provide a door mounting with aspring which will be of such a. shape and so arranged that it willoccupy, but little space within the stove structure and will permit theuse of a narrow stove front.

A further object of the invention is to provide, in connection with sucha door mounting, a spring which will have but l1t tle movement and will,therefore have a long life.

Other objects of the invention will appear as the construction isdescribed in detail.

In the accompanying drawings Fig. 1 is a front elevation of portions ofthe stove front and of the lower left hand corner of the door; Fig. 2 isa rear elevation of portions of the stove front and of the lower righthand corner of the door; Fig. 8 is a section taken on the line of 3-3 ofFig. 2 looking in the direction of the arrow; Fig. 4: is a section takenon a line H of Fig. 2 looking in the direction of the arrows; and Fig. 5is a vertical section taken through one of the mountings and showing thedoor in its open position.

In these drawings we have illustrated one embodiment of our inventionand have shown the same as applied to the door of an oven forming a partof a stove, and having a front 1, which is herein characterized as thestore front. This stove front is provided with an opening 2, whichconstitutes a door way, and which may be closed by a door 3. In thepresent construction the door 3 fits within the doorway and, in itsclosed position; rests upon the lower edge thereof. As here shown thedoorway has at each lower corner thereof a downward extension orrecess-d and the door 3 has downwardly extending portions 5 which fitinto these recesses. The stove front also has flanges 6 which are spacedin the rear of the front and extendinwardly beyond the respective edgesof the doorway and thus form stops to limit the rearward movement of thedoor and against which the door rests when in its closed position.Ateach lower corner of the doorway the front is provided with an'opening 7, which extends through the flange, and the door is providednear its lower edge with rearwardly and downwardly extending parts orarms 8 which project through the respective openings 7 to points in therear of the stove front. ltigidly secured to the stove front near thelower corners of the doorway, and preferably cast integral with thefront, are rearwardly extending guides or cams 9, the rear edges ofwhich are curved. In the present instance these guides are substantiallysemi-circular in shape and the rear edges thereof are curved about anaxis spaced a short distance above the lower edge of the doorway. Eachof the arms 8 has near its rear end a laterally extending part, such asa stud 10, which overlies the curved edge of the adjacent guide and isarranged to ride over that guide as the door is moved toward or from itsclosed position. Preferably, the stud has mounted thereon a stop orwasher 11 which engages the outer surface of the guide and holds the armagainst lateral displacement with relation thereto. Because of onearrangement of the guide with relation to the door it will be apparentthat the movement of the door toward its open position will cause thestud 10 to ride over the curved surface of the guide and thus lift thearm and the lower edge of the door to the positions shown in Fig. 5.Each arm 8 has at its rear end a projection or lug 12 which is arrangedto engage the flange at the upper edge of the opening 7 and thus limitthe forward move.- .rent of the door. The stove front is providedadjacent to each opening 7 with a recess 13, the forward surface ofwhich is curved and constitutes forwardly facing bearing surface. Thedoor has near its lower corners parts 14, which are curved to fit withinthe recesses 18 and which constitute bearing members to cooperate withthe bearings 13. it will be noted that the arrangement of the bearingmembers on the at and on the door is such as to permit of the upwardmoven'ient of the bearing llU some distance: tow the rear of thestoveti'ont atone sideot thedoorway; The endsof this :coil extend hi'Wa'rdly,-as shown at 16' andal'l, and constitute forwardly divergingarnis,-by- 1118MB of which the coilis con nected 1with'thestove frontand door arm, respectively. The lower arr-1, 16,- is pivotally'conne'cted withthe adjacenfidoor arnr 8 near the'rear endoi' thelatter and; in'the present instance, the arrn 16 has a hook shaped endportion, 18, which engages over the stud 10. The upper arm lT 'ot'th'espring has a la tera'lly extending portion or trun= nion 19- which isjournalled in-a recess in a bearing: block 20 which rigidly but dotachably secured to a lugQl carried-by the stove front; It will beapparent that when the door arm 8 moves up'vmrdly the lower" springarin16 will be carried therewith, thus compressing the coil 15 oi thespring. Because otthe: pivotai connections between the spring arms andthe front, respectively, iillGSG 'fllHlS will not be flezrcd at pointsadjacent to said connections and there willd e no appreciable distortionofthe spring other than the compression of' the coil.Gonsequentlythespring will havebut little inoveinent and there will'be'little tendency for it to crystallize andbreak.
